I try to record a voice message with lifecam vx-1000 but when I try to playback to check the message I don't hear anything. I have checked all the volumes & they're all fine. so why can't I record a voice message? & why aren't my sound recorder & lifecam in sync?

Check in the skype window itself if the microphone is set to the cameras built in mic. The mic may also have gotten wet or simply ceased to function.

You do not give much info - for example eg, Your OS and if you have a laptop you would have 2 mics
Try setting you webcam mic as default

If you have a laptop and a webcam you have 2 mics - you need to set your webcam mic as default.

First of all you have to check if its on. If it was you would've been hearing your voice but if you have VISTA then right click on the speaker thing and it will show all these things you're going to have to go to the Microphone settings and change it to be LIFECAM VX 1000 so you could talk into the camera (You change the settings) Thats what i think is wrong,

I have seen situations in the past where a woman especially would not modulate her voice well enough to make good sound on her mic, other then that, make sure your mic volume is set fairly high. Also if the situation is not cleared by the previous two suggestions look for newer audio drivers for your system ( whatever that may be ), a.k.a. motherboard audio driver or sound card drivers depending on what hardware you have installed
